Description

Technical Field

[0001] This utility model belongs to the field of barcode reader technology, and in particular to a multi-head barcode reader device. Background Technology

[0002] The processing of cigarette packs requires the use of multi-head barcode readers to read the barcodes on the surface of the cigarette packs. Existing multi-head barcode readers use air jets to clean dust and other debris from the surface of the cigarette packs in order to improve reading efficiency. However, the effect of air jet cleaning of dust and other debris is weak, and dust and other debris are very likely to remain on the surface of the cigarette packs, obscuring the barcodes. This causes the multi-head barcode readers to be unable to read the barcodes on the surface of the cigarette packs, reducing the reading efficiency of the device.

[0003] A search of related technologies revealed a Chinese patent document (authorization announcement number CN221804711U) describing a multi-head barcode reader, comprising a moving device and a barcode reader assembly. The barcode reader assembly is slidably connected to the surface of the moving device, and track columns are slidably connected to the left and right sides of the moving device. This multi-head barcode reader, through the use of a protective frame installed on the side of the barcode reader assembly in conjunction with a gas nozzle, provides a certain degree of protection and cleaning during the operation of the multi-head barcode reader. This protects the entire barcode reader assembly and prevents foreign objects on the material surface from obstructing the barcode scanning, thus affecting the scanning effect. The moving device, in conjunction with the track columns, provides horizontal and vertical movement adjustment for the entire barcode reader assembly, ensuring structural mobility while maintaining the optimal reading distance between the barcode reader assembly and the material to maximize reading accuracy. However, this device does not consider the relatively weak effect of air jet cleaning of dust and other debris, making it easy for dust and other debris to remain on the surface of the cigarette packs, obscuring the barcode and reducing the device's reading efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multi-head code reader to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-head barcode reader, comprising:

[0006] The mounting frame is in the shape of an inverted U, and a multi-head barcode reader for reading the barcodes of tobacco sticks is installed on the top wall inside the mounting frame.

[0007] The support frame is U-shaped, and a conveyor is installed on the bottom wall inside the support frame.

[0008] The cleaning assembly includes two fixed frames and movable rods. The fixed frames are inverted U-shapes. Both inner side walls of the fixed frames are slidably connected to the movable rods. The two movable rods are connected to the adjacent sides of the movable frames. Movable rods are movably connected to the inner side walls of the movable frames. Movable plates are connected to the top surfaces of the movable rods. Rotating rods are connected to the top surfaces of the movable plates. A bottom-recessed limiting plate is connected to the bottom surface of the movable frames. A brush plate is inserted into the inner cavity of the limiting plate. Several brush bristles are connected to the bottom surface of the brush plate.

[0009] Preferably, the top surface of the support frame is connected to the mounting frame and two fixed frames respectively, and the end face of the rotating rod is connected to the output shaft of the rotary motor through a coupling.

[0010] Preferably, the fixed end of the rotary motor is connected to a connecting plate by bolts, and the two end faces of the connecting plate are connected and fixed to two fixed brackets.

[0011] Preferably, the brush plate has two rotating plates on top, and fixed bearings are embedded in and fixedly connected to the top surface of the rotating plates.

[0012] Preferably, the inner ring of the fixed bearing is interference-fitted with a fixing rod, and the bottom surfaces of the two fixing rods are connected to the brush plate.

[0013] Preferably, the top surface of the fixed rod is connected to an abutment plate, and the bottom surfaces of the two abutment plates abut against the rotating plate.

[0014] Preferably, a rubber plate is connected to the bottom surface of the rotating plate, and the top surface of the rubber plate is embedded and fixedly connected to the fixing rod.

[0015] Preferably, the bottom surfaces of the two rubber plates are in sliding frictional contact with the limiting plate, the top surface of the limiting plate has two through slots for the rotating plate to pass through, and the side of the support frame is connected to four symmetrically arranged mounting ears.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] This multi-head barcode reader uses a conveyor to transport cigarette packs to a designated location. The multi-head barcode reader then reads the barcodes. However, since dust and other debris easily adhere to the surface of the cigarette packs, obscuring the barcodes and hindering reading efficiency, a cleaning device removes this debris, improving reading efficiency. The device starts a rotary motor, whose output shaft rotates, driving a rotating rod. The rotating rod and movable rod, located at the top and bottom of the movable plate, are staggered, allowing the movable rod to move along the inner wall of the moving frame. Under the limit of the movable rod, several brush bristles reciprocate laterally during transmission, cleaning the dust and debris from the cigarette pack surface.

[0018] This multi-head barcode reader has bristles connected to the bottom of the brush plate that are prone to bending after prolonged use, reducing their effectiveness in cleaning dust and other debris adhering to the cigarette surface. Two rotating plates, connected by fixed bearings, rotate around a fixed rod. Once the two plates reach a designated position, they detach from the limiting plate via a groove on its top, facilitating easy disassembly of the brush plate and replacement of the bristles. This improves the device's usability and enhances the cleaning effect on cigarette surface. A rubber plate provides anti-slip protection; once the rotating plates and rubber plate fix the relative positions of the brush plate and limiting plate, they prevent wobbling and further improve the structural stability of the device components.

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] To address the issue of multi-head barcode readers having limited effectiveness in cleaning dust and other debris with air jets, thus reducing their efficiency in reading cigarette barcodes, please refer to [link to relevant documentation]. Figures 1 to 6 The structure of the device body includes:

[0032] Mounting frame 1 is in the shape of an inverted U. The top inner wall of mounting frame 1 is equipped with a multi-head barcode reader 2 for reading barcodes on tobacco strips.

[0033] The support frame 3 is U-shaped, and a conveyor 4 is installed on the inner bottom wall of the support frame 3;

[0034] Cleaning component 5 includes two fixed frames 6 and a movable rod 7. The fixed frames 6 are inverted U-shaped. The two inner side walls of the fixed frames 6 are slidably connected to the movable rods 7. The two movable rods 7 are connected to the adjacent sides of the movable frames 8. The inner side wall of the movable frames 8 is movably connected to the movable rods 9. The top surface of the movable rods 9 is connected to the movable plate 10. The top surface of the movable plate 10 is connected to the rotating rod 11. The bottom surface of the movable frames 8 is connected to the bottom recessed limiting plate 12. The inner cavity of the limiting plate 12 is inserted into the brush plate 13. The bottom surface of the brush plate 13 is connected to several brush bristles 14.

[0035] In this embodiment, the multi-head barcode reader 2 is connected to the inner top wall of the mounting frame 1 by bolts, so that the mounting frame 1 provides a positional fixation function for the multi-head barcode reader 2. The fixed end of the conveyor 4 is connected to the inner bottom wall of the support frame 3 by bolts. The conveyor 4 transports the cigarette packs to a designated position, and the multi-head barcode reader 2 reads the barcodes of the cigarette packs to achieve continuous barcode reading and improve the barcode reading efficiency of the device. Since dust and other debris easily adhere to the surface of the cigarette packs, when dust and other debris obscure the barcodes, the multi-head barcode reader 2 cannot read the barcodes on the surface of the cigarette packs, reducing the barcode reading efficiency of the device. The cleaning component 5 is provided to clean the dust and other debris adhering to the surface of the cigarette packs. To improve the barcode reading efficiency of the device, the rotating rod 11 and the movable rod 9, which are connected to the top and bottom surfaces of the movable plate 10 respectively, are staggered. When the rotating rod 11 rotates, the movable rod 9 moves in a circle around the rotating rod 11 as the axis, moving along the inner cavity of the movable frame 8, realizing the lateral reciprocating movement of the movable frame 8, which in turn drives the two movable rods 7 to move. The two fixed frames 6 respectively fix the lateral movement path of the two movable rods 7, improving the structural stability of the device components. During the transmission process, the brush plate 13 drives several brush bristles 14 to move laterally reciprocatingly, cleaning the dust and other debris adhering to the surface of the cigarette pack, thereby improving the barcode reading efficiency of the device.

[0036] Specifically, the top surface of the support frame 3 is connected to the mounting frame 1 and two fixed frames 6 respectively. The end face of the rotating rod 11 is connected to the output shaft of the rotary motor 16 through a coupling. The fixed end of the rotary motor 16 is connected to the connecting plate 15 through bolts. The two end faces of the connecting plate 15 are connected and fixed to the two fixed frames 6.

[0037] In this embodiment, the support frame 3 provides support and fixation for the mounting frame 1 and the two fixed frames 6, and the provided rotary motor 16 provides power so that the output shaft of the rotary motor 16 drives the rotating rod 11 to rotate during the rotation process.

[0038] Specifically, the brush plate 13 has two rotating plates 18 on its top. The top surface of the rotating plate 18 is embedded with a fixed bearing 19. The inner ring of the fixed bearing 19 is interference-fitted with a fixed rod 20. The bottom surface of the two fixed rods 20 is connected to the brush plate 13. The top surface of the fixed rods 20 is connected to an abutment plate 21. The bottom surface of the two abutment plates 21 abuts against the rotating plate 18.

[0039] In this embodiment, the fixed bearing 19 fixes the rotation position of the rotating plate 18 and provides conditions for the relative rotation of the rotating plate 18 and the fixed rod 20. The abutment plate 21 abuts against the top surface of the rotating plate 18 to prevent the fixed bearing 19 from being damaged when the rotating plate 18 is subjected to upward extrusion force, thereby improving the structural stability of the device components.

[0040] Specifically, the bottom surface of the rotating plate 18 is connected to a rubber plate 22, the top surface of the rubber plate 22 is embedded and fixedly connected to the fixing rod 20, the bottom surfaces of the two rubber plates 22 are in sliding friction contact with the limiting plate 12, the top surface of the limiting plate 12 has two through slots for the rotating plate 18 to pass through, and the side of the support frame 3 is connected to four symmetrically arranged mounting ears 17.

[0041] In this embodiment, the rotating plate 18, the rubber plate 22, and the abutment plate 21 extend to the top of the limiting plate 12 through the inner wall of the through groove of the limiting plate 12, causing the rotating plate 18 to rotate, thereby making the bottom surface of the rubber plate 22 contact the limiting plate 12. During the transmission process, the position of the brush plate 13 is fixed, and it is also convenient to disassemble the brush plate 13 after the rotating plate 18 rotates to the designated position, preventing the brush bristles 14 from bending after long-term use, improving the cleaning effect of dust and other debris on the surface of the cigarette pack, and thus improving the barcode reading efficiency of the device. The top surface of the mounting ear 17 is provided with a threaded through groove for bolt thread connection, providing conditions for the installation and fixation of the device.

[0042] The multi-head barcode reader 2, conveyor 4, and rotary motor 16 are all existing technologies. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0043] Working principle

[0044] When using this multi-head barcode reader, the user places the cigarette pack on the top surface of the conveyor belt of the conveyor 4, starts the conveyor 4 to transport the cigarette pack, starts the rotary motor 16, and drives the rotary rod 11 to rotate during the rotation of the output shaft of the rotary motor 16. Under the connection of the movable plate 10, the movable rod 9 moves circumferentially on the inner side wall of the movable frame 8, and the movable frame 8 moves laterally back and forth. At the same time, it drives the two movable rods 7 to move laterally. The two fixed frames 6 fix the movement path of the two movable rods 7 respectively. During the transmission process, the brush plate 13 drives a number of brush bristles 14 to clean the dust and other debris adhering to the surface of the cigarette pack.

[0045] After the cigarette pack is moved to the designated position, the multi-head barcode reader 2 reads the barcode of the cigarette pack, so that the two rotating plates 18 rotate to the designated position with the two fixed rods 20 as the axis respectively, and the rotating plates 18 and the rubber plate 22 extend into the inner wall of the through groove of the limiting plate 12. During the transmission process, the brush plate 13 and several brush bristles 14 are disassembled and replaced.
